From: Mengdong Lin Date: Fri, 13 Feb 2015 11:21:25 +0000 (+0800) Subject: ASoC: Intel: set initial runtime PM status to active for ACPI-enumerated ADSP X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7bd345c9e87d879d696c6843fe200b60c2051c84;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ASoC: Intel: set initial runtime PM status to active for ACPI-enumerated ADSP The ADSP on Braswell/Baytrail is an ACPI device. This patch sets its initial runtime PM status to active. Otherwise, its initial status is suspended and runtime_suspend ops will not be called after probe and thus cannot further trigger ACPI _PS3 (D3) method to put the device into low power D3cold state.
